No doubt in my mind. Wreckless challenge, could have pulled out, straight red......until I watched it in slow motion. Then I realised that although Birchall was a little late, he was attempting to play the ball. Nyarko's speed and skill made it look a lot worse. If I was his coach, I'd probably not want him to make those kind of challenges. As we can see, Nyarko easily saw the challenge coming and if Birchall hadn't fouled him, Nyarko would have space to run into.
